Pacific Yew Taxus brevifolia Forest Biology Campus Tree Walk Notes of Interest The Forest Biology Campus Tree Walk is a 1-2 hour tour of some of the interesting trees on the UVic campus. It was difficult to choose from among the many species planted, and we hope the walk will inspire you to identify more of the trees that you find on your way. In formal garden areas, tree signs are placed at the base of the tree on a metal post. In other areas, signs are hung fairly high on the main stem or a lower branch of the tree. Part of the fun is finding the sign! Trees on the Campus Tree Walk are listed in order below. The common name is followed by the scientific name and the family to which the tree belongs. The natural range of each tree is described and some distinguishing features are listed. Other information of interest is included. 1) Douglas-fir - Pseudotsuga menziesii (Pinaceae) An evergreen conifer native to the coastal regions of western North America, from west-central British Columbia, south to central California. There is considered to be a coastal and an interior variety in B.C. Douglas-fir is not a true fir (true firs are in the genus Abies) thus the common name is hyphenated. Douglas-fir is distinguished by its thick, furrowed, fire-resistant bark, needles arranged all around the stem, pointed buds and three-pronged bract emerging from between the scales in the mature cone. Coastal Douglas-fir is a very large tree, some say the second tallest in the world after Coast Redwood. It commonly lives more than 500 years and occasionally more than 1,000 years. 2) Southern Magnolia - Magnolia grandiflora (Magnoliaceae) An evergreen angiosperm also known as bull bay. Southern magnolia is native to the southeastern United States, from coastal North Carolina south to central Florida, and west to southeast Texas. It is distinguished by its large, white, lemon-scented flowers, glossy, leathery leaves, and fuzzy brown buds. 3) Bigleaf Maple - Acer macrophyllum (Aceraceae) A deciduous angiosperm native to the Pacific coast of western North America from southern Alaska to southern California. Bigleaf maple is distinguished by the largest leaves of any maple, typically 15-30 cm across, with five deeply-incised, palmate lobes. We understand that it is possible to make maple syrup from the sap of Bigleaf maple, but it requires a lot of reduction. 4) Vine Maple – Acer circinatum (Aceraceae) A deciduous angiosperm native to western North America from southwest B.C. to northern California, always within 300 km of the Pacific Ocean. Vine maple is distinguished by its shrubby form, sympodial growth (terminal bud usually lacking) and almost circular leaves with 7-9 palmate lobes separated by narrow notches which become red or yellow in autumn. 5) Red Alder - Alnus rubra (Betulaceae) A deciduous, angiosperm native to western North America, from southeast Alaska to central coastal California. Red alder is the world's largest species of alder, reaching heights of 20-35 m. The name derives from the bright rusty red color that develops in bruised or scraped bark. Red alder roots are host to the nitrogen fixing actinomycete Frankia. This association allows the tree to grow in nitrogen-poor soils, even old road beds. In disturbed moist forest areas, red alder can rapidly form a dense cover. A russet dye can be made from a decoction of the bark and was used by First Nations people to dye fishing nets so as to make them less visible underwater. Red alder can be recognized by its leaves which have coarse, blunt teeth and margins rolled under. The fruits are conelets. 6) Oriental Plane-tree – Platanus orientalis (Platanaceae) A deciduous, angiosperm native to Eurasia from the Balkans to India which crosses with American sycamore (Platanus occidentalis). The Oriental Plane-tree is grown widely for shade. This specimen at UVic is reputed to have been grown from a seed brought from the tree under which Hippocrates taught medicine on the island of Kos. Leaves of the Oriental Plane tree can be distinguished from those of maple because the bottom-most veins are not palmate. The puzzle-like bark and globose fruits are also distinguishing features. 7) Garry Oak – Quercus garryana (Fagaceae) A deciduous, native, angiosperm ranging from southern California to the southwestern corner of British Columbia. Also known as Oregon white oak, Garry oak is a deeply-rooted, drought tolerant species. It can be distinguished from English white oak by its shiny, dark-green upper leaf surface, leaf stalks more than 1 cm long, and solitary or paired acorns on short stalks less than 5 mm in length. Garry oak tends to have short, forked trunks compared to the tall, straight trunk of English white oak. The acorns are edible after soaking to leach out bitter tannins. Small green or yellow galls can often be found on the undersides of leaves. The galls are formed by the oak around colonies of wormlike larvae belonging to one of several species of tiny wasps. A common wasp species responsible for these galls is Cynips maculipennis 8) Finnerty Apple – Malus sylvestris (Rosaceae) The Finnerty family were among the earliest settlers and farmers in the Mount Tolmie area in the 1860s and ‘70s. In the 1890s, Mike and Mary Ann Finnerty, along with John and Hanna Finnerty, ran a successful orchard and dairy farm on land that is now the UVic campus. Two domestic apple trees from the family orchard still stand in the quadrangle just south of the Cornett Building. They are reputed to be a particular variety of apple – the Finnerty apple. 9) Arbutus – Arbutus menziesii (Ericaceae) A drought-tolerant, evergreen angiosperm found on the west coast of North America, from British Columbia (mainly Vancouver Island) to California. It is distinguished by its glossy, evergreen leaves, red, papery, peeling bark, white, urn-shaped flowers, and clusters of orange-red berries. Like Douglas-fir, its species name was given it in honour of the Scots naturalist Archibald Menzies, who noted it during George Vancouver's voyage of exploration. 10) Black cottonwood – Populus trichocarpa (Salicaceae) A deciduous angiosperm native to western North America, from Alaska to northern California. Black cottonwood is also known as western balsam poplar and is the largest species of poplar, growing to 50 m tall. It is distinguished by ovate leaves with whitish undersurfaces and short, round petioles, resinous fragrant buds, and deeply furrowed, grey bark on older trees. The seeds are covered by white, fluffy hairs, and are released prolifically in June. 11) Monkey puzzle – Araucaria araucana (Araucariaceae) An evergreen conifer native to southern Chile and Argentina, Monkey puzzle is the hardiest species of Araucaria. Its range is now restricted to a small area approximately 200 km long x 50 km wide in the Andes, and a few patches in the coastal cordillera of Chile. Monkey puzzle is distinguished by its triangular, sharply pointed leaves. It has very regular, whorled growth when young, but self-prunes and becomes flat-topped when old. Trees are usually dioecious (separate male and female trees). This specimen is a male and will produce pollen cones, but the female cones contain edible seeds. Trees can grow to 50 m height and 2 m diameter. The name is said to have come from a British garden owner who said “it would puzzle a monkey to climb that” (if there were any monkeys in its native range). 12) Western redcedar - Thuja plicata (Cupressaceae) An evergreen conifer native to the west coast of North America from southern Alaska to northern California; and to inland valleys in southern B.C. to western Montana. Western redcedar is the provincial tree of B.C., and is distinguished by its scale-like leaves, red-brown, fibrous bark, and seed cones with leathery, paired, spine-tipped scales.

  • Phosphatidylserine
    Cognitive Vitality Reports® are reports written by neuroscientists at the Alzheimer’s Drug Discovery Foundation (ADDF). These scientific reports include analysis of drugs, drugs-in- development, drug targets, supplements, nutraceuticals, food/drink, non-pharmacologic interventions, and risk factors. Neuroscientists evaluate the potential benefit (or harm) for brain health, as well as for age-related health concerns that can affect brain health (e.g., cardiovascular diseases, cancers, diabetes/metabolic syndrome). In addition, these reports include evaluation of safety data, from clinical trials if available, and from preclinical models. Phosphatidylserine Evidence Summary May promote cognitive function and protect from decline, especially for DHA-enriched phosphatidylserine. It has a good safety profile but has limited bioavailability. Neuroprotective Benefit: Mixed evidence from clinical trials, and considerable bias in results reporting. Has poor bioavailability and it’s unclear how well it gets into the brain. Aging and related health concerns: No clear rationale or data. One study reported a minor increase in mobility in elderly, but effect can’t be clearly tied to phosphatidylserine. Safety: Well-tolerated with no serious adverse events reported in short trials. May slightly reduce blood pressure. Information on long-term safety is not available. 1 What are they? Phosphatidylserine (PS) is a class of phospholipids that help to make up the plasma membranes in the brain. Varying the levels and the symmetry of PS in cell membranes (i.e. on the inside or outside of a membrane) can affect signaling pathways that are central for cell survival (e.g. Akt, protein kinase C, and Raf-1) and neuronal synaptic communication [1].

  • Amelanchier Alnifolia. Araucaria Araucana
    Woodland Garden Plants The present-day cultivation of large areas of single annual crops such as wheat might seem, on the surface, to be a very productive and efficient use of land (average wheat yields this century have increased more than three-fold to over 3 tons per acre). When other factors are taken into account, however, it can be argued that this is a very unproductive and unsustainable use of the land. A woodland, on the other hand, might seem to be a very unproductive area for human food (unless you happen to like eating acorns). By choosing the right species, however, a woodland garden can produce a larger crop of food than the same area of wheat, will require far less work to manage it and will be able to be sustainably harvested without harm to the soil or the environment in general. I do not intend to go into any more details of the pros and cons of annuals versus perennials here. If you would like more information on this subject then please see our leaflet Why Perennials. One of the main reasons why a woodland garden can be so productive is that such a wide range of plants can be grown together, making much more efficient use of the land. The greater the diversity of plants being grown together then the greater the overall growth of plant matter there is. Thus you can have tall growing trees with smaller trees and shrubs that can tolerate some shade growing under them. Climbing plants can make their own ways up the trees and shrubs towards the light, whilst shade- tolerant herbaceous plants and bulbs can grow on the woodland floor.

The aging process in perennial plants is not well defined, yet can 16 have implications on production and yield of valuable fruit and nut crops. Almond, a relevant nut 17 crop, exhibits an age-related disorder known as non-infectious bud failure (BF) that affects 18 vegetative bud development, indirectly affecting kernel-yield. This species and disorder present 19 an opportunity to address aging in a commercially-relevant and vegetatively-propagated, 20 perennial crop threatened by an aging-related disorder. In this study, we tested the hypothesis 21 that telomere length and/or TERT expression can serve as biomarkers of aging in almond using 22 both whole-genome sequencing data and leaf samples collected from distinct age cohorts over a 23 two-year period.

  • Trees: That Can Present a Litter Problem
    Visit us on the Web: www.gardeninghelp.org Trees: That can Present a Litter Problem The following trees drop fruit and/or other debris that can make them undesirable in some locations. Scientific name Common name Comments Aesculus hippocastanum Horsechestnut Golfball-sized fruit can be hazardous. Seeds are also toxic and should not be confused with the edible chestnut. Premature leaf drop from leaf blotch disease can be unsightly. Catalpa speciosa Catalpa Large numbers for dropping seed pods can present a litter problem. Ginkgo biloba Ginkgo Female ginkgo trees produce a fruit that has a very offensive odor. Male-only cultivars do not produce fruit and are readily available. Gleditsia triacanthus Honeylocust The fruit is large, abundant, and messy. Also, honeylocust trees have large potentially painful thorns. There are thornless trees, often listed as G. t. var. inermis (or G. t. forma inermis), but sprouts from the roots of grafted cultivars may produce thorns. These trees are susceptible to several diseases and insect pests. Gymnocladus dioica Kentucky coffeetree This is a valuable native Missouri tree but some owners may consider its leaves and seed pods a litter problem. Juglans nigra Black walnut Black walnut trees leaf out late and lose their leaves early; consequently, they are bare much of the year. The nuts can be messy and their husks stain skin, clothing and sidewalks. The roots produce juglone, a chemical which is toxic to many other plants. Liquidamber styraciflua Sweet gum Sweet gum fruits are abundant, difficult to clean up, fall from the tree over a period of several months and can be hazardous in pedestrian traffic areas.

  • Ginkgo Biloba Maidenhair Tree1 Edward F
    Fact Sheet ST-273 November 1993 Ginkgo biloba Maidenhair Tree1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION Ginkgo is practically pest-free, resistant to storm damage, and casts light to moderate shade (Fig. 1). Young trees are often very open but they fill in to form a denser canopy. It makes a durable street tree where there is enough overhead space to accommodate the large size. The shape is often irregular with a large branch or two seemingly forming its own tree on the trunk. But this does not detract from its usefulness as a city tree unless the tree will be growing in a restricted overhead space. If this is the case, select from the narrow upright cultivars such as ‘Princeton Sentry’ and ‘Fairmont’. Ginkgo tolerates most soil, including compacted, and alkaline, and grows slowly to 75 feet or more tall. The tree is easily transplanted and has a vivid yellow fall color which is second to none in brilliance, even in the south. However, leaves fall quickly and the fall color show is short. GENERAL INFORMATION Scientific name: Ginkgo biloba Pronunciation: GINK-go bye-LOE-buh Common name(s): Maidenhair Tree, Ginkgo Family: Ginkgoaceae Figure 1. Middle-aged Maidenhair Tree.
